"In this tutorial I will be detailing how to generate analogue voltages using a Raspberry Pi and an external Digital to Analogue Converter (DAC) to control the brightness of an LED. Although the Raspberry Pi can interface with various low-level hardware using it’s GPIO lines, SPI, I2C and serial UART interface, it does not have an DAC interface for generating analogue voltage levels. Instead the user must use an external DAC device controlled by one of the available low-level hardware interfaces, such as SPI and I2C."

"Presenting PiMony, a smart remote prototype built on a Raspberry Pi! As prototypes go, this is very… prototypey! It is quite large and kludgy. The goals at the moment are to learn more about the hardware side, and try out ideas for both hardware and software. Then work on the size, look and feel!"

"If you are a beginner to Raspberry Pi and were looking for a simple hardware project, then look no further. This tutorial will show you to develop a python based robot which avoids obstacles and navigates freely. Obstacle avoiding robots are fairly common and easy to make."

"I imagine you’re here because you have heard about the internet enabled fishtank, the world’s most advanced taking aquarium. I made it as a one-off project purely to push my technical skills to the limit and create something awesome."

"I developed this WSN for a coursework on my MSc and I’m hoping others will find this useful or at least interesting 🙂 I’ve just installed the first parts of this WSN back home to collect sensor data from various outbuildings and it will be part of my new Arduino controlled greenhouse project. I’ll try to port the storage and reporting backend to a Raspberry Pi later this week, initial trials seem to suggest that it should cope well with this task for my size of network."

"Back in late February I saw this post on the Raspberry Pi site: http://www.raspberrypi.org/school-weather-station-project/ . They had created Raspberry Pi Weather Stations for Schools. I totally wanted one! But at that time they are not publicly available. Well, I wanted on and I didn’t feel like shelling out hundreds of dollars for an existing 3rd party system."

"The presented home monitoring system consists of a star like structure of wireless nodes. This means that one node, the main node, collects information from the other nodes and forwards them to Raspberry Pi. The other nodes act just like wireless sensors – periodically measure physical values around the flat and send the measurements to the main node. "

"Raspberry Pi is a great project computer, it’s cheap ($35), runs Linux (or Risc OS) and has lots of resources available aroudn it. When mine arrived, I didn’t really know what to use it for, but then it hit me: I can build an emulator box for all the NES and SNES games that I loved to play as a child."

"The PiDP-8/I is a modern replica of the 1968 PDP-8/I computer. …It’s an open-source hardware project, so schematics, design files & software are available here. During 2015, I will also offer the PiDP as a kit. There are great economies of scale with some of the parts when they are bought in bulk so group ordering parts for a kit makes sense."

" Some extra hardware and software changes the Raspberry Pi into a DVB-S digital TV transmitter. The code and diagrams are released under the GPL license. This project would not have been possible without the pioneering done by Jean-François Fourcadier, F4DAY."
